Abstract (en)
[origin: US2022295054A1] A method for in-loop sample offset filtering in a video decoder is disclosed. The method includes extracting at least one loop filtering parameter from a coded video bitstream for a reconstructed sample of a first color component in a current picture reconstructed from the coded video bitstream, the at least one loop filtering parameter comprising a flag, and determining based on the flag a type of sample offset filter to be applied to the reconstructed sample of the first color component, the type of sample offset filter being either a predefined sample offset filter type or an encoder-derived sample offset filter type. The method further includes identifying a target sample offset filter to be applied to the reconstructed sample of the first color component based at least on the determined type of sample offset filter, and filtering the reconstructed sample of the first color component based on the target sample offset filter and a plurality of reconstructed reference samples of a second color component to generate a filtered reconstructed sample of the first color component.
